ELECTRICAL HEATING- APPLIANCE.

Specification 01' Letters Patent.

Patented May 21, 1918.

Application filed October 26, 1917. Serial No. 198,621.

To all whom it may concern:

Be it known that I, Cnmuo E. HELLER, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Electrical Heating Appliances; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to certain new and useful improvements in electrical heating units and has for its primary object to provide means whereby any gas range may be readily converted into an electrical range.

A more specific object of the present invention is to provide an electrical heating unit disposed in a pan shaped container which has means on its bottom for detach ably engaging the supporting rod which extends transversely across the burner receivin frame of a gas range.

IVith the abo ve and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawing, I have. illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Figure l is a top plan view of my invention secured to a gas range, the gas range being shown in conventional lines.

Fig. 2 is a. side plan view of my invention separate from the range.

Fig. 3 is a front elevation view of my invention, and

Fig. 4 is 9. dia. ra-nnnatic view of the heating elements an means for varying the degree .of heat generated by the elements Referring now more particularly to the accompanying drawing, 1 designates a gas range of usual construction having transverse burner supporting rods 2 upon which the usual gas burners 3 rest, andmy invention is desi nod to take the place of the humor 3 and consists of a pan shaped container 4 which has secured transversely to its bottom a transverse member 5 which has its ends directed downwardly andibifurcated as at 6 for engagement with rod 2.

For retaining container 4 in its proper position on rod 2 a brace member 7 has its inner end secured centrally to member 5 as at 8 and has its portion 9 directedalong the side of container 4 and secured thereto, and has its outer end 10 directed downwardly to pass over and rest upon the gas supply pi pc 11 of the range. By this construction, the container 4 is held from displacement, and disposed in the container are two series of heating coils l2 and 13, which have a com mon wire 14- leading to a central contact plug 14 of a three way male plug 15 and leading from coils 12 is a wire it? which connects with the contact 16 of. plug 15, and leading from coils 13 is a wire 17 leading to a contact 17 of plug 15.

A female plug 18 is rovided with a pair of contacts 19 UOHDQCtGtFWllIll a common wire 20 and a central contact 21 connected with a wire 22, which wires 21 and 22 lead through a suitable control switch23 connected with a source of electrical energy by means of connection 24, and provided in connection 2-1 is a suitable breakable plug which is carried by the extreme end of portion 10. As best shown in Fig. 4, when it is desired to have a low heat in container 1-, plug 18 is placed in position relative to plug 15 so that contact 21 will engage contact 1.6 and one contact 19 will engage contact 14. When it is desired to have a medium heat, plug 18 is in the position depicted in Fig. 4, contacts 14 and 17 engaging contacts 19 and 21 respectively, and when it is desired to have a maximum supply of heat,c0ntact 21' engages contact 14 and contacts 19 engage contacts 16 and 17'.

From the foregoing description taken in connection witltthe accompanying drawing it will be readily apparent that by my invention an ordinary gas range can be readily converted into an electrical range and that the same is simple and compact in its general arrangement.

I claim v 1. An electrical heating element comprising, in combination, a pan-shaped container, a transverse member secured to th bottom of the container, and having its ends downturned and bifurcated to engage a supporting rod, a-support secured centrall to said transverse member and to thesi e o'f the container, said support extending laterally from the container and then being downturned to engage a supporting pipo, heating coils disposed in said container, electrical connections carried by the down-turned portion of said supporting member and connected with said heating coils, and means in said electrical connections for varying the heat generated by the coils in the container, substantially as described.

2. An electrical heatin ing a pan-shaped container, heating coils disposed in said container, a transverse member secured to the l, ,ttmn side thereof element comprisand directed laterally and o n ardly o engage a supporting bar, a brace member secured to the transverse member and to h 2?](18 of the container, said brace member beng rovided at its outer and with a control switch a source of electrical supply c nnected with said switch, and an electrical connection betwen the heatin coils and said switch.

In testimony that claim the foregoing I, have hereunto set my hand at Milwaukee, in the county of Milwaukee, and State of Wisconsin.
